From b23908d3c48a37c46c6a26df2cdeab1610b360ba Mon Sep 17 00:00:00 2001
From: Simon Glass <sjg@chromium.org>
Date: Sun, 17 Jun 2018 14:09:42 +0200
Subject: [PATCH] firmware: dmi: Add access to the SKU ID string
This is used in some systems from user space for determining the identity
of the device.
Expose this as a file so that that user-space tools don't need to read
from /sys/firmware/dmi/tables/DMI
